[0059] During drilling:

[0060] When grasping the drill rod, the feeding drill rod oil cylinder 11 contracts to drive the rubbing wheel device 9 on the first rotating shaft 8 and the lower manipulator 10 to rotate backward and laterally. Then the rotary drill rod motor 22 rotates to drive the second rotating shaft 19 and the two drill rod clamping plates 20 to rotate, and the drill rod placed on the drill rod clamping groove 21 is transferred to the ports of the execution ends of the rubbing wheel device 9 and the lower manipulator 10. Then the rubbing wheel oil cylinder 96 and the drill rod grasping oil cylinder 103 extend, and then drive the upper jaw body 104 and the third rubbing wheel 99 to move, so that the upper jaw body 104 cooperates with the lower jaw body 101, and the first rubbing wheel 97, the second rubbing wheel 98 and the third rubbing wheel 99 cooperate to grasp the drill rod tightly.

[0061] When the rod is lifted, the feeding cylinder 11 extends to drive the rotating shaft 1 to rotate the wheel rubbing device 9 with a drill rod and the lower manipulator 10 forward and laterally, sending the drill rod into the clamping mechanical claw 65 of the drill rod holder 6. At this time, the drill rod is aligned with the center of the rock drill 7. The advancing cylinder 5 extends to push the drill rod holder 6 to slide forward along the advancing beam 1. The second steel cable 17 will also pull the rock drill 7 to slide forward along the advancing beam 1. The rock drill 7 starts to rotate forward. During the process of the second steel cable 17 pulling the rock drill 7 forward, the front end execution shaft of the rock drill 7 screws into the connecting sleeve at the rear end of the drill rod and then connects with it. The operator installs a drill bit at the front end of the drill rod. The clamping cylinder 64 contracts, causing the clamping mechanical claw 65 to grip the drill rod tightly. The wheel rubbing cylinder 96 and the drill rod clamping cylinder 103 contract to release the drill rod. Then the feeding cylinder 11 contracts to drive the wheel rubbing device 9 and the lower manipulator 10 on the rotating shaft 1 to retreat to grab the next drill rod.

[0062] The advancing cylinder 5 continues to push the drill rod holder 6 forward. The second steel cable 17 will also continue to drive the rock drill 7 to slide forward along the advancing beam 1. The front end of the drill rod will extend into the through hole on the front end plate 2. During the advancing process, the drill rod will be drilled into the construction site under the action of the rock drill 7. Until the connecting sleeve at the rear end of the drill rod extends into the drill rod jamming device 4, the clamping cylinder 64 extends to open the clamping mechanical claw 65. After the rock drill 7 continues to advance and the connecting sleeve at the rear end of the drill rod enters the drill rod jamming device 4, stop the rock drill 7 and extend the drill rod jamming cylinder 41 to clamp the connecting sleeve at the rear end of the drill rod through the caliper sleeve 42.

[0063] When connecting the drill rods:

[0064] After the first drilling is completed, the advancing cylinder 5 retracts to drive the drill rod holder 6 to retract. When the advancing cylinder 5 retracts, the rock drill 7 rotates in reverse so that the rock drill 7 separates from the first drill rod. The rock drill 7 finally retracts to the rear end of the advancing beam 1.

[0065] Then repeat the operations of grabbing and lifting the rod until the drill rod for the hole to be drilled is connected to the execution end of the rock drill 7. Then the advancing cylinder 5 continues to push the drill rod holder 6 forward. The second steel cable 17 drives the rock drill 7 to slide forward along the advancing beam 1. The rock drill 7 rotates forward to screw the front section of the drill rod for the hole to be drilled into the connecting sleeve of the drill rod clamped in the drill rod jamming device 4 to achieve connection.

[0066] Then continue the drilling operation until the connecting sleeve at the rear end of the second drill rod extends into the drill rod jamming device 4. Stop the rock drill 7 and extend the drill rod jamming cylinder 41 to clamp the connecting sleeve through the caliper sleeve 42.

[0067] Repeat the above operations until the drilling operation is completed. The length of a single drill rod is 2135 mm. There are 9 drill rods in the drill rod bin seat 18 + 1 drill rod at the rock drill, and the total drilling depth is 10 * 2.135 - 0.165 = 21.185 meters. The minimum drilling diameter is 51 mm and the maximum is 76 mm.

[0068] When removing the drill rod:

[0069] The propulsion cylinder 5 retracts to drive the drill rod holder 6 and the rock drill 7 to retract. The rock drill 7 will drive the first drill rod in the drill hole to withdraw from the drill hole until the connection sleeve at the rear end of the second drill rod in the drill hole retracts into the drill rod jamming device 4. The drill rod jamming cylinder 41 extends to clamp the connection sleeve of the second drill rod through the caliper sleeve 42.

[0070] The feed cylinder 11 extends to drive the friction wheel device 9 and the lower manipulator 10 on the first rotating shaft 8 to rotate forward and laterally. Then the drill rod grasping cylinder 103 extends, and then drives the upper jaw body 104 to move, so that the upper jaw body 104 and the lower jaw body 101 cooperate to grasp the first drill rod tightly. The rock drill 7 rotates in reverse, and the propulsion cylinder 5 continues to retract to drive the rock drill 7 to separate from the connection sleeve of the first drill rod. The rock drill 7 finally retracts to the rear end of the propulsion beam 1.

[0071] The friction wheel cylinder 96 drives the third friction wheel 99 to move, so that the first friction wheel 97, the second friction wheel 98 and the third friction wheel 99 cooperate to grasp the first drill rod tightly. The drill rod grasping cylinder 103 contracts to separate the upper jaw body 104 from the lower jaw body 101 and loosen the first drill rod. Then the friction wheel motor 910 rotates and the drill rod removing cylinder 93 extends. The friction wheel motor 910 drives the first friction wheel 97 and the second friction wheel 98 to rotate through the first driving gear 912 and the first transmission gear 914. When the second friction wheel 98 rotates, it drives the third friction wheel 99 to rotate through the second transmission gear 96, and then separates the front end of the first drill rod from the connection sleeve at the rear end of the second drill rod in the drill hole. The drill rod removing cylinder 93 will make the first drill rod move backward while rotating until the first drill rod is completely separated from the second drill rod.

[0072] The feed cylinder 11 contracts to drive the lower manipulator 10 and the friction wheel device 9 holding the drill rod on the first rotating shaft 8 to retract. Then the friction wheel cylinder 96 operates to place the drill rod into the drill rod jamming groove 21 of the drill rod jamming plate 20 between the drill rod bins 18. The rotary drill rod motor 22 rotates to drive the second rotating shaft 19 and the two drill rod jamming plates 20 to rotate to the next empty position, waiting for the recovery of the next drill rod.

[0073] The propulsion cylinder 5 extends and the rock drill 7 rotates forward. The second steel cable 17 will drive the rock drill 7 to move towards the drill rod jamming device 4, and the front end execution shaft of the rock drill 7 will be screwed into the connection sleeve of the second drill rod. Then the drill rod jamming cylinder 41 contracts, the propulsion cylinder 5 retracts, and the rock drill 7 will drive the second drill rod in the drill hole to withdraw from the drill hole. The rock drill 7 continues to retract until the connection sleeve at the rear end of the third drill rod in the drill hole retracts into the drill rod jamming device 4. The drill rod jamming cylinder 41 extends to clamp the connection sleeve of the third drill rod through the caliper sleeve 42.

[0074] Then repeat the above drill rod removing operation to remove all the drill rods.

[0075] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
